Just chiming in.

I've also heard about openwrt scaling issues.

I know at nycresistor we had failures under large numbers of folks
operating with the fonera2.0n units.  Work solid at home... but
scaling... nopers.

I have a buffalo unit with atheros i do dev work on.  I suppose I
could try to do some stress testing on it.

buffalo wzr-ag-300h unit.
